Introduction
The objective of this experiment was to verify the energy equation for a flow in a lateral
constriction in a rectangular channel.
Theory
When there is a lateral constriction, if it is slender enough, the flow may become critical at the

Objectives
In this experiment, we are trying to verify the theory of hydraulic jump. The theory states
that when increasing Froudes number, the jump will increase proportionally. Using the results
obtained in this lab, the specific energy and specific for
